why do we know more today than we did yesterday? One reason is that scientists engage in research. The excitement of discovering new knowledge through research is illustrated by studying the bond strength of gaseous titanium monosulfide. Gaseous TiS molecules as well as gaseous titanium and sulfur atoms are produced by the vaporization of the high melting crystalline titanium monosulfide at temperatures near 2000Â°K. The procedures for producing and measuring temperatures in this region are shown. Analysis of the mass spectrum gives the relative concentrations of atomic Ti and S, and of TiS molecules. A torsion effusion apparatus gives data on the total gas pressure at a series of temperatures. From these data, we calculate the bond strength of gaseous TiS. But at least as many new questions are raised as are answered. We don't run out of questions in research.
